SPRlNG SHADE-ROLLER.

SPECIFICATION forming part of Letters Patent No. 466,413, dated January 5, 1892.

Application filed December 30, 1890. Serial No. 376,215- (N model.)

To all whom it may concern.-

Be it known that I, STEWART HARTSHORN, a

' citizen of the United States, and a resident of Short Hills, in the county of Essex and State of New Jersey, have invented anew and useful Improvement in Spring Shade-Rollers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making a part ofthis specification.

My improvement relates to that class of fixtures for shade-rollers described in the Letters Patent granted to me December 24, 1889, No. 417,783, in which the end plate or cup attached to the roller is stamped or struck up from metal in two parts, and in which the end of the stick on which the spring is mounted rests in the cup on the plate.

In the drawings, Figure is a detached view of the two parts forming the end plate. Fig. 2 is a View of the complete end plate in position on the stick or spindle and showing the spring connected to the plate.

In my improvement the end plate is struck up or stamped from thin metal in two parts, which are afterward put together to form the complete plate. 7

One of the parts A is of a general oblong shape, and is formed with a vcentral hole 0, through which the spear. on the end of the stick passes, and has around this hole a cup or recess D,- in which the end of the stick rests. On opposite sides of this cup or recess are formed two lugs E E, through which the end of the spring passes, and by which the latter is connected to the end plate and roller, as is shown in Fig. 2. These lugs E are made by a bend or fold of the metal formed in stamping. Beyond the-lugs the ends of the piece are formed to lit the back and edge of the other part of the plate B, as shown, the narrow part F resting against the back of the plate B and the edge H resting in the recess or cut-away portion H of the plate. This edge H when the two parts A and B are together, completes the edge of the plate, as is shown in Fig. 2. One end of the piece F is prolonged, as f, and rests against the back of the plate B, and the other end, as G, isloent up at right angles and enters into the wood of the roller and prevents the end plate or cup from turning around. The section or part A thus contains in one piece and struck up or stamped at one operation the central hole 0, the recess D for the stick, the lugs E for attaching the spring, and the projections G. This section A is fastened to the back of the plate B, which carries the pawls P. The plate B is stamped from thin metal, ready shaped, as shown, and the pawls P are then riveted on in the usual manner. tach the section A to the plate B, it is only necessary to place the former in position on the back of the latter,'with the edgesHin the cut-away portions H, and press the two parts together, when the edges H will fit tightly over the edge of the plate B and hold the two sections together without other manipulation. To form the complete end plate, therefore, the two sections or parts A, containing theseveral features above described, and B, having the pawls, are stamped or struck up separately and then united by merely pressing or springing the section A onthe back of the section B, when the end plate is ready for the stick R and spring S. The end of the stick rests in the recess D on thersection A, with the spear T passing out freely through the holes 0 and O in the sections A and B.

As fully explained in my former patent, No. 417,783, this furnishes a more even and perfect bearing for the stick and insures a truer revolution of the roller on the stick. This recess D is made large enough to furnish a broad bearing for the end of the stick. The spring S is then fastened by being passed through thelugs E and the end of the spring e turned up so as to rest on the side of the lug, as is shown in Fig. 2. The stick, spring, and end plate are now ready to be connected with the roller in the usual manner.

lVhat I claim as new is In a spring shade-roller, the end plate or disk consisting of the section A, having the large hole 0, cup or recess D, lugs E, and projections G, substantially as described, and the plate B, having the pawls P and provided with the large hole 0', struck up from metal and connected together, as and for the purpose set forth.
